{[M(NH3)6][Ag4M4Sn3Se13]}∞ (M=Zn, Mn): Three-dimensional chalcogenide frameworks constructed from quaternary metal selenide clusters with two different transition metals

Two 3D framework selenides, [M(NH3)6][Ag4M4Sn3Se13] (M=Zn (1), Mn (2)), constructed from quaternary metal selenide clusters, have been solvothermally synthesized and are photoactive under visible light illumination.
